Thanks, much appreciated.

Yeah it seems less trivial than I would have wanted/expected to get this done, without adding e.g. a cmake level check for it. Alternatively, a strategy like "include all of <sys/types.h> and <unistd.h> and similar that are available, and then add a typedef if MSVC" might work too, but that's not exactly neat either.
